Add optional full URL handling for custom instances

[mbestavros]

This PR adds some additional parsing logic to allow custom instance fields to be full URLs.

The primary benefit from the additional parsing is that custom instances can specify properties they couldn't before - specifically, port numbers and plain HTTP, if desired. This is particularly handy for users self-hosting their own frontends.

If the custom instance field is not populated with a valid URL, the extension will fall back to the old behavior - in other words, it should be fully backwards compatible.

Walkthrough

The changes involve modifications to the createRedirectRule function within the updateRules function in src/background.js. The instance parameter is now parsed to extract the protocol, hostname, and port from a URL format, with added error handling to ensure robustness. The construction of the transform object for redirect properties has been updated to use the parsed URL components dynamically, enhancing flexibility in the generated redirection rules.

Poem

In the code where rabbits play,
Redirects now find their way.
With protocols parsed, oh what a sight,
Flexibility hops, taking flight!
Error handling, a wise little trick,
Ensures our rules are clever and quick! 🐇✨

416-425: Excellent enhancements to the createRedirectRule function! LGTM.

The changes introduce several key improvements:

1. URL parsing:

   • Allows the instance parameter to accept full URLs, providing more flexibility to users.
   • Extracts the protocol, hostname, and port from the URL, enabling support for custom protocols and ports.
   • Provides a fallback to "https" protocol and null port if parsing fails, ensuring graceful handling of invalid URLs.

2. Dynamic transform object:

   • Constructs the transform object dynamically based on the parsed URL components.
   • Enables the function to generate redirect rules that match the provided URL format.
   • Maintains backward compatibility by defaulting to "https" and null port when parsing fails.

3. Error handling:

   • The try-catch block ensures that parsing failures are caught and handled gracefully.
   • Prevents the function from throwing errors and breaking the redirect rules.

These enhancements greatly improve the flexibility, robustness, and user experience of the createRedirectRule function. Great job!

438-438: Correct usage of the transform object.

The transform object is properly used in the returned redirect rule to specify the scheme, host, and port for the redirect. This is consistent with the changes made to construct the transform object dynamically based on the parsed URL components.

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
